Hi folks. I have a 5050 that worked fine until one day it didn't. It lights up but won't come out of protection. On the power supply board, two fuse resistors are burnt and measure at 0 ohms, so they're shorted. They are R612 and R613 and I believe they're 10 ohms. I am guessing I need to replace some of the diodes in the diode bridge. Can I replace those with 1N4005s, or should I go higher? If that doesn't take care of it I will go from there, but this has mostly new caps on the PS board already and I am guessing it's a diode issue.
